Urban stereo road

Abstract

The invention is an urban three-dimensional road, which solves the problem of mutual interference of crossing traffic. The first-floor road and the second-floor road have one-way roads (9), (10) and courtyards (20), the one-way roads separated by the courtyard (20) have connecting passages (11), and the one-way roads have connecting ground floor roads and first-floor roads 1, the approach road (13) of the first-floor road and the second-floor road, the patio (20) along the axis of the main road section (22) that can be directly connected at the intersection divides the first-floor road and the second-story road of the main road section (22) into Separated one-way streets (9), (10), and the disconnected one-way streets (9), (10) of the first-floor road (3) of the secondary road section are connected by approach bridges across the patio (20). Part of the one-way street (9) and (10) on the second-story road (4) of the secondary road section are connected and cover part of the patio (20) on the first-floor road (3), and the middle part of the connected road is raised upwards to form a horizontal The arch bridge (21) across the second-story road of the main road section (22) and the patio (20) on the axis, the flat parts on both sides are connected with the second-story road of the main road section (22), and there are approach roads (13) and Layer-by-layer connection.

Description

Technical field: [0001] The present invention relates to urban viaducts, especially to cross viaducts. Background technique: [0002] The existing elevated road, such as the technical solution named "Urban Three-dimensional Road" and the patent number ZL99114942.4, is based on the rapid growth of motor vehicles in my country in the late 1990s, but the serious lagging of urban traffic infrastructure caused serious urban traffic congestion and parking difficulties. The invention of "urban three-dimensional road" solves the problem that the previous urban elevated roads are difficult to go up and down, and makes it form an organic combination with the original ground roads without destroying the various functions of the original ground roads. Parking, and solve the difficult problem of parking at the same time. Although the "urban three-dimensional road" has the two advantages of solving the problem of vehicle getting on and off and parking within the road itself, the node tha...

Problems solved by technology

In this way, when the traffic flow on the secondary road section is small, the degree of interference to vehicles in the direction of the main road section will not be obvious. If the traffic flow in the four directions is relatively large and there is no distinction between primary and secondary, it is obviously not satisfactory. Necessary, because continuous vehicles driving in parallel will form stagnation and congestion near the connecting channel 11, and eventually the entire line will be affected
